Infinite loop in Apache MINA

  • Disclosed: 03.11.2021
  • Updated: 11.10.2026 11:21

In Apache MINA, a specifically crafted, malformed HTTP request may cause the HTTP Header decoder to loop indefinitely. The decoder assumed that the HTTP Header begins at the beginning of the buffer and loops if there is more data than expected. Please update MINA to 2.1.5 or greater.
